Statement : `FeCl_2` is more covalent than `FeCl_3`
Explanation : Higher is the charge on cation more is deformation of anion , more is covalent character .

Options

A. `S` is correct by ` E` is wrong .
B. `S` is wrong but `E` is wrong .
C. Both `S` and `E` are correct and `E` is correct explanation os ` S` .
D. Both `S` and ` E` are conrrect and `E` is correct explanation os `S`.

Explanation

To analyze the statement and explanation provided regarding the covalent character of `FeCl_2` and `FeCl_3`, we can follow these steps:

### Step 1: Understand the Compounds
- Identify the oxidation states in both compounds:
- In `FeCl_2`, iron (Fe) has a +2 oxidation state (Fe²⁺).
- In `FeCl_3`, iron (Fe) has a +3 oxidation state (Fe³⁺).

### Step 2: Apply Fajans' Rules
- Fajans' rules state that the covalent character of an ionic compound increases with:
- Higher charge on the cation.
- Smaller size of the cation.
- Larger size of the anion.

### Step 3: Compare the Charges
- Compare the charges of the cations:
- Fe²⁺ (in `FeCl_2`) has a lower charge than Fe³⁺ (in `FeCl_3`).
- According to Fajans' rules, as the charge on the cation increases, the covalent character also increases.

### Step 4: Conclusion on the Statement
- Since Fe³⁺ has a higher charge than Fe²⁺, `FeCl_3` should exhibit more covalent character than `FeCl_2`.
- Therefore, the statement "FeCl₂ is more covalent than FeCl₃" is **incorrect**.

### Step 5: Evaluate the Explanation
- The explanation states: "Higher is the charge on cation, more is deformation of anion, more is covalent character."
- This explanation is consistent with Fajans' rules, which indicate that a higher charge on the cation leads to greater covalent character due to increased polarization of the anion.
- Thus, the explanation is **correct**.

### Final Conclusion
- The statement is **incorrect**.
- The explanation is **correct**.
- The explanation does not justify the statement.

### Summary:
- **Statement**: FeCl₂ is more covalent than FeCl₃ - **Incorrect**
- **Explanation**: Higher charge on cation increases covalent character - **Correct**
